Abstract

SE DESCRIBEN UN METODO Y UN APARATO PARA OBTENER UN INDICATIVO DE MEDICION DE LA RELACION ENTRE DIMENSIONES DE PARTICULAS ESFERICAS EN SUSPENSION. LA CONDUCTIVIDAD DE LA SUSPENSION SE MIDE PARA DOS ORIENTACIONES DISTINTAS DE LAS PARTICULAS ENTRE PUNTOS (5, 6) Y SE UTILIZA LA DIFERENCIA ENTRE LAS CONDUCTIVIDADES MEDIDAS COMO INDICACION DE LA RELACION ENTRE LAS DIMENSIONES DE LAS PARTICULAS. LA ORIENTACION DE LAS PARTICULAS SE ALINEARA EN UNA MEDICION Y, EN LA OTRA, SE PUEDE ALINEAR Y SER TRANSVERSAL RESPECTO A LA DIRECCION DE LA PRIMERA ORIENTACION O AL AZAR. ALTERNATIVAMENTE, PUEDE HABER UNA SOLA ORIENTACION ALINEADA PERO MEDICIONES DE LA CONDUCTIVIDAD TRANSVERSALMENTE DIRIGIDAS.
